So VM_BUG_ON_PAGE(PagePoisoned(page)) is\ntriggered.  This can be reproduced by below steps:\n\n1.Offline memory block:\n\n echo offline > /sys/devices/system/memory/memory12/state\n\n2.Get offlined memory pfn:\n\n page-types -b n -rlN\n\n3.Write pfn to unpoison-pfn\n\n echo <pfn> > /sys/kernel/debug/hwpoison/unpoison-pfn\n\nThis scenario can be identified by pfn_to_online_page() returning NULL. \nAnd ZONE_DEVICE pages are never expected, so we can simply fail if\npfn_to_online_page() == NULL to fix the bug."
